王府井海港城工程(图1)位于北京王府井大街北端,建筑面积为19.6万m2,建筑高度为39.6 m,地下5层,地上11层,槽底标高为-25.380 m,集水坑共30个,其中最深处标高为-28.280 m。根据地勘报告,在建场区内存在3层地下水,分别为上层滞水、潜水和层间水,其中上层滞水水位埋深为4.56~5.12 m,水位标高为42.250~41.300m;潜水水位埋深为18.59~19.16 m,水位标高为28.850~27.380 m;层间水水位埋深为23.23~23.57 m,水位标高为24.460~22.930 m。
The Wangfujing Harbor City Project (Figure 1) is located at the northern end of Wangfujing Street in Beijing with a building area of 196,000 m2 and a building height of 39.6 m. It has 5 underground floors and 11 floors above the ground. The elevation of the bottom of the tank is -25.380 m. One, of which the deepest elevation of -28.280 m. According to the geological prospecting report, there are 3 layers of groundwater in the construction site area, namely upper strata stagnant water, submersion and interlayer water, of which the upper strata stagnant water depth is 4.56 ~ 5.12 m and the water level elevation is 42.250 ~ 41.300m; Depth of 18.59 ~ 19.16 m, water level elevation of 28.850 ~ 27.380 m; inter-layer water depth of 23.23 ~ 23.57 m, water level elevation of 24.460 ~ 22.930 m.
